I guess all the similar large storms that hit the upper-east coast were because of global warming too...even if they occurred before global warming was supposed to have started.

There was a meteorologist on TWC who evidently studied such things and he was quite specific that because of how the water temps in the Pacific and Atlantic were entering a CYCLE of being at odds (he cited the 50's as another time period when the same thing happened) that we would see many of these kinds of storms over the next few years until things go back to normal. They asked him if it was global warming and he was quite clear that it was something that happens from time to time, whether we pumped out CO2 or not...
